a)carbon bonds in food are broken, which releases energy.
b)weathering breaks down rocks into chemicals like sulfur and nitrogen. c)consumers make food using light energy from the sun.
d)energy is absorbed as heat when plants make food.

A) Carbon bonds in food are broken, which releases energy.

Explanation:

Ecosystem is a biotic community where living beings interact among themselves and with their non living physical environment. The living beings either produce their own food by photosynthesis or chemosynthesis or obtain food from other organisms.

The carbon bonds in the food get broken so as to make the food simple in composition for digestion. The energy is released after the bonds are broken.
